Router vs Switch - I am still confused (alien.top)

Probably a very basic question but confused the hell out of me - say if I have 100mb internet at home, and scenario one, a router with 100mb port speed and I connect two PCs to it, each has a 100mb NIC card, is it true that ignoring other factors I should be able to get close to, if not 100mb connection on each of the PCs? On the other hand, scenario 2, if I have a (unmanaged) switch and I connect the PCs to the switch I would only ended up getting 50mb each on each of the PCs (i.e., the switch essentially "halved" my internet speed if I connect 2 PCs to it, 1/3 if I connect 3 PCs to it, etc)?

Thanks a lot, yes indeed that's the question I have but I wasn't just not sure how to ask it. So if I understand it clearly, roughly speaking if there is a device on the switch that saturated the pipeline then all other devices are slowed, but in router with the QoS settings you could guarantee a minimum bandwidth for each of the device? So if I do not use any sort of QoS settings would that essentially make router almost like a switch in terms of routing traffic? I understand obviously routers these days have a lot more functionality like VPN gateway or printer server but let's just ignore those for the sake of discussion.
